Preliminary Results

An intensive field survey on aquatic insects of Me Linh Station for Biodiversity in Vinhphuc province was conducted in December 2015. Specimens were collected at 8 different sites and aquatic insects were collected both quantitatively by Surber net and qualitatively by hand net, pond net. As a result, a total of 110 aquatic insect species belonging to 98 genera, 49 families and 9 orders were recognized. Among these, the order Ephemeroptera had the highest species number with 26 species, followed by Odonata with 25 species, Trichoptera with 18 species, Coleoptera with 15 species, Hemiptera with 11 species, Diptera with 9 species. Lepidoptera, Plecoptera and Megaloptera had the lowest of species number, represented by 3 species of Lepidoptera, 2 species of Plecoptera and 1 species of Megaloptera. Besides, the quantitative analysis results and the functional feeding groups were provided.

Dry And Rainy Seasons

Study on the functional feeding group (FFG) structure of aquatic insects in upstreams of Da Nhim river to understand the ecological functional groups in the watershed. The study investigated two headwater streams (A and B) of upper Da Nhim river in the dry and rainy seasons 2013). Quantitative sampling, diversity indices, grouping the FFGs and analysing correlation between the FFGs conducted in each season. Results showed that: (1) Shannon - Weiner indices (H') were 3.0-4.4, and Simpson indices (λ) were 0.06-0.13; (2) The FFG structure included five groups: collector - garthering (cg) (46 %), scrapper (sc) (31 %), collector - filtering (cf) (12 %), predator (p) (8 %) and shredder (sh) (3 %); (3) The correlations were possitive and stability in seasons. Shredder (sh) implied the intact riparian vegetation; and the occurrence of predators in both two seasons, implied the nutrient balance in the stream ecosystem. The FFG structures should be documented in the continuing lower reaches of the Da Nhim river to fulfill data in the whole system of Dong Nai river
